g This invention relates generally to cop winding machines, and moreparticularly to machines for winding double-taper ended cops for use inloom shuttles and the like.

The object of the present invention is to eliminate the necessity forproviding machines of this type with a plurality of different sizes ofprogression wheels in order to wind cops of different sizes on the samemachine.

In order to secure the elimination referred to, I have provided machinesof this type with an oscillating traverse bar adjustable at each of itsends to correspond with the size of the cop desired and with the size ofthe progression wheel arranged to form the cop.

Other objects of the invention will appear as the detailed descriptionthereof proceeds.

Referring to the drawings:

The reference numeral 1 designates the base of the winding part of themachine. Standards 2 and 3 extend upwardly from the base 1 and areprovided with the usual hearings in which the traverse bar 4 androtating spindle 5 are operably mounted.

A screwthreaded bar 6 which forms a continuation of the traverse bar 4has its outer end mounted to slide in a sleeve 7 which is swiveled bymeans of an annular bushing 8 to swing in an outboard bearing 9, thebushing 8 being secured to the sleeve 7 by means of a screw 10. 'Theother end of the bar 6 is provided with a horizontal slot 11 (see Figure5) which receives a plate 12 fixed to the end of the traverse bar 4.

The plate 12 is provided with a slot 13 in which is slidably mounted apin 14 secured to the end of the bar 6 and forming the usual pin andslotconnection between the traverse bar proper and the screwthreadedextension thereof which carries the progression wheel. The plate 12extends rearwardly of the machine and is provided with a downwardlyextending arm 15 terminating in a cylindrical lug 16 which slidablyembraces a rod 17 extending between the standards 2 and 3 (see Figure 4)and acts to prevent rotation of the traverse bar during thereciprocations thereof.

Suitably secured to the back of the arm 15 is an upwardly extendingsupport 17 provided with a horizontal branch 18 and a downwardlyextending support 19 for an adjusting screw 20 forming part of stopmechanism to regulate the movement of the shaper end of the bar 6 towardand from the spindle 5.

The adjusting screw 20 passes freely through an aperture 21. formed inthe support 19 and is screwthreaded into a downwardly 2 extending part22 of a stop member 23 which is slidably mounted on the horizontalbranch 18 and may be clamped in position thereon by means of a screw 24.As shown clearly in Figure 5, the stop member 23 is provided with lugs25 and 26 embracing the branch 13 and is also provided with a slot 27through which passes a shank 28 of screw 24: which is screwthreaded intothe branch 18.

The screw 24 is a clamping screw :tor holding the stop member 23 in anyposition on branch 18 to which it may be adjusted by means of the screw19. The downwardly extending part 22 is long enough to extend into thepath of movement of the pin, 14 which as previously described is securedto the end oi the bar 6 and extends upwardly through the slot 13. Itwill be obvious from inspection of the drawing. that adjustment of thestop member 23' controls the displacement or" the bar '6 relative to thetraverse bar & and thereby, so far as the shaper end of the machine isconcerned, controls the diameter of the cop.

The outboard bearing 9 for the bar 6 is pivotally mounted on thestandard 2 (see Figures Sand 9') to swing about a pivot screw 29 and hasthe vertical part thereoi provided with an arcuate slot 30 through whichpasses the screwthreaded end 31 of a clamping bolt 32 suitably securedin the upper part of the standard 2. A wing nut 33 engages the screwthreaded end 31 or" the bolt 32 and serves to lock the bearing 9 in anyposition of angular. adjustment about its pivot 29.

From the description sotar it is apparent that the traverse bar isadjustable at each of its ends toward and from the spindle 5. The objectof this adjustment is to obviate the use of dilierent sized progressionwheels for winding different sized cops. The adjustment of the bar 6'toward and from the spindle 5 is etlected by means of gauges and 35. Thegauge at is wider than the gauge 35 as it ought to be in order tocompensate for the taper of the spindle 5 and insure parallelism betweenthe axes of the bar 6 and spindle 5 when the progression wheel is freeof the shaper plate. In setting the bar 6. it is more convenient to usetwo gauges, but a single gauge ma be used to set each end separately,one of such gauges being illustrated in Figure 10.

Each of the gauges comprised a wide end 36 and a narrow end 37 and haspositioning lugs 38 and 39 extending from each side thereof. The lugs 38and 39 are adapted to rest on the bar 6 and the spindle 5. The wide end36 is used to space the bar 6' relative to the narrow end of the spindle5 while the narrow end 37 of the gauge is used to space the other end ofthe bar 6 relative to the wide end of the spindle 5. hen the gauges areso used and positioned on bar 6 and spindle 5, the stop pin 14; on theshaper end of bar 6 occupies a predetermined position in the slot 13. Inthis position of the stop pin it, the adjusting screw 20 is turned so asto bring the arm 22 of the stop member 23 hard up against the rear sideof stop pin 14. The clamping screw 24 is then turned down into clampingposition to lock the stop member in adjusted posit-ion on the branch 18of the support 17.

When the parts are adj Listed as described, it is obvious that thediameter of the wound cop will vary with the extent of displacement ofthe pin 1-1 relative to the axis of the traverse bar 4:, providing thesame progression wheel is used on the screwthreaded bar 6.

In order to provide for the shaping of the conical end or the cop at theheel thereof, a shaper plate 10 is adj ustably mounted on the plate 12which is lined to the traverse bar 4;. The shaper plate a0 is providedwith a slot 41 which is slidable relative to a pin 42 projecting fromthe traverse barl. The pin and slot connection just described arePI'OVlCiGQ to limit the inward and outward movement of the shaper platerelative to the traverse 1. The shaper plate 10 may also be adjustedlaterally oi the plate 12; and to eilect this adjustment, the plate 12is provided with an arcuate slot 13 (see Figure 2) arranged immedia elyunder a straight slot let on the sha per plate ll) (see Figures 1 and Inorder to clamp the plate in adjusted position on the plate 12, the lowerpart of the plate 12 has seated thereon a clamping plate which isprevented from movement relative to said plate by means of small dowelsand 16 and corresponding holes formed in the plate 12 to receive-saiddowels. In proper position below the slots 13 and 1 1 the clamping plate14-" is provided with a screwthreaded aperture 46 to receivecorresponding screwthread'ed shan 47 or a clamping screw e8. Theoperation of the adjusting mechanism described will be obvious to thoseskilled in the art by inspection of the various figures of the drawing.

The modification shown in Figure 7 is merely the converse of that justdescribed. In this modification, the stop member-d9 (see Figures 6 and7) is secured adjustably to the horizontal branch 50 of a support 51which is formed integral'with the front end of the plate 12. The stopmember 419 is provided with a slot 51 adapted to receive the shank 52 ofa clamping screw 53 which is screwthreaded into the horizontal branch 50of the support 51.

The downwardly extending arm 54 of the stop member 49 extends into thepath of the stop pin 14:" of the traverse bar 6 and the stop with thearm 54 may be adjusted as a whole by the screw 55 which is screwthreadedinto the downwardly extending part 56 of the stop member 49 and has itsend contacting with the face of the support 51. The adjusting andclamping operation of this modification is similar to that of the othermodification and need not be further described. The stop member 49 isprovided with an in wardly projected lug 57 which slides under thebranch 50 of the support 51 to prevent rising of the stop member 4-.9upwardly from the branch 50. The member 49 is also provided with aflange 58 engaging the side of the branch 50 to prevent rotation of themember 49 laterally on the branch 50. An

I indicator 59 may be formed on one side of the stop member 49 tocooperate with the scale on the branch 50 and thereby indicate theadjustment of the end of bar 6 relative to the. cop spindle.
